Act as a small business advisor. Write a one-page business plan for {{business_idea}} in {{city_and_country}}. What I know so far: {{known_details}}. My starting budget: {{starting_budget}}. Quality bar: specific to this place and customer, and readable by a bank or partner in two minutes. Estimate break-even with the formula shown (monthly fixed costs divided by contribution margin per sale) using my numbers, and label every figure you had to assume. Do not invent local market data; list what I should research instead. Return these sections: problem and customer, offer and pricing, why this location, competitors and how we differ, how customers will find us, startup costs and monthly running costs, break-even estimate, key risks, and the first five steps for the next 30 days. Add a note to confirm licenses, tax registration, and funding decisions with a qualified local advisor.
